  • 1. The Germanna Library Collection Analyzed (Using WorldCat Collection Analysis from OCLC)By Karen A. Bowers Introduction The WorldCat Collection Analysis Service can compare catalog records with those of any comparisonpeer school, who has decided to participate in the comparison analysis. Letters to as many as tenschools may be sent to obtain permission. As soon as permissions have been obtained, they must besent to OCLC. In the Administrative module, schools may be set up using the OCLC code for the schoolsselected. OCLC monitors this process and makes this option available. In the case of Germanna, we also set up a group which contained all the selected comparisonschools. This was the control group from which we could determine the percentage of materials thatwere in our collection and compare it with the percentage in the other schools. We determined thepercentage by dividing the Germanna collection number by the VCCSGroup number for each majorsubject heading. In order to make this comparison however, there is a basic process that must becompleted. In the Limit Analysis area, filters must be created. I found that entering the appropriateLibrary of Congress classification numbers was the most assuring filter. There is a way to just use thegeneral filter for an OCLC subject category, but then the limit description is much less informative. Using the “Limit Analysis” option, we were able to gather collection counts from each of thecomparison schools and the group as a whole. We searched by the general subject categories that areused in analyzing “My Library.” We also created filters for narrower subjects, such as VeterinaryMedicine and Dentistry. Additional analysis can be made on demand by creating the filters andanalyzing each school’s data listed under the “Data to analyze” tab. Two subject analysis pages were created in Excel. One compared the peer schools by collectioncount in the OCLC subject categories and the other compared the peer schools by subject andpercentage of holdings in the VCCS control group. From this, it can be determined that the followingsubject collection totals are at least half the size of the peer schools. Another way to say this is that weneed to add twice the titles in these subject areas in order to approach a comparable collection with theother schools. Biological Sciences Communicable Diseases Government Documents
  • 2. Performing Arts Art and Architecture Music Sociology.Other subject areas that proved to be very low in the collection count are the Physical Sciences and Pre-Clinical Sciences. It was necessary to consult the OCLC Conspectus in order to understand thesecategories, as they do not align with the Library of Congress Classification System. Physical Sciences Astronomy QB0-9999 Physical Sciences Physics, General QC0-80 Physical Sciences Weights & Measures QC81-114 Physical Sciences Experimental Mechanics QC120-168 Physical Sciences Constitution & Properties of Matter QC170-219 Physical Sciences Acoustics, Sound QC220-250 Physical Sciences Heat QC251-338 Physical Sciences Optics, Light, Radiation QC350-496 Physical Sciences Electricity, Magnetism, Nuclear Physics QC501-798 Preclinical Sciences Human Anatomy QS0-681 Preclinical Sciences Physiology QT0-275 Preclinical Sciences Biochemistry QU0-220 Preclinical Sciences Pharmacology QV0-835 Preclinical Sciences Microbiology and Immunology QW0-949 Preclinical Sciences Parasitology QX0-675
  • 3. Preclinical Sciences Clinical Pathology QY0-490 Preclinical Sciences Pathology QZ0-380In Art and Architecture, our collection was not on the same level as the other schools. For four of the five schools, we cocollection four times to be on the same level. Interestingly enough, J.Sargeant Reynolds had only 12% compared to overand over 30% in one school. Clearly, Germanna’s 5 % is too low for this subject area. Music is a related field where welow at only 8%. However, I do not know that our curriculum supports these fields enough to merit a great increase. Art boexpensive because of the graphics. Music is not as expensive, but may not be in high demand. Our library should purchaareas though, as these subjects do support academic excellence and a good general education. There is a new certificate program for Dental Assistants, which will begin in Jan. 2012, and in light of the fact that ouprogram is part of the NVCC program, it is time to increase the book collection in this subject area. The Dental Assistant pprogram or three semesters. Students will get a CDA (Certified Dental Assistant) certificate. Our cooperative partner for tprogram had a materials count of 133. Germanna has only 25 titles in Dental subjects. Doubling this collection is recommpopular program. Here is a graph produced from analyzed data to show the need for increasing the Dentistry collection. Dentistry 250 200 150 100 Dentistry 50 0 GCC JSRCC JTCC LFCC PCC TNCC VCCS Group
  • 4. Steps to analyzing the collection:Identify subject areas by graphing the collection with your filtered numbers created in the WorldCat Collection Analysis sfollowing analysis, we concentrated on STEM subjects. STEM stands for Science, Technology, Engineering and Mathemagraph below, that Germanna’s collection was surprisingly high in Chemistry when compared to these subject fields in ouThe question is how does this compare with the peer institutions? 18 16 Agriculture 14 Veterinary Medicine Biological Sciences 12 Chemistry 10 Communicable Diseases 8 Dentistry 6 Engineering and Technology 4 Geography 2 Mathematics 0 Medicine GCCLet’s look at the Chemistry data across the board.

  • 5. There is no error in having more Chemistry texts than the other schools, but instead it should be noted that the ChemistGermanna’s strengths. The next question that might be asked is. “How current are these Chemical texts?” Do we neestrength? To answer this question, I would consult “My Library” in the WCAS.It would be beneficial to purchase more recent titles in this area to maintain the current strength in this field. See the Vtitles in Organic Chemistry and other Chemical subject areas. All community colleges may be searched and the most recretrieved first in a subject keyword search. See the following snap shot of such a search.The best way to compare colleyear is to conduct a subject key word search in the VCCSlinc or online catalog. Because it is a kmost current items will be retrieved first. When subject keywords are selected, results will be very relevant, because weterminology of the Library of Congress.
  • 6. ConclusionIn conclusion, the WCAS does assist in finding subject areas to analyze or to analyze selected subjects as desired. The fonecessary. 1. Contact peer institutions to retrieve permission to compare collections. 2. Send permission emails or letters to OCLC for set up. 3. OCLC will contact you, when they are ready for you to set up the Administrative module. 4. Create the Libraries within the Administrative Module. 5. Create a Control Group which contains the holdings of all the comparison schools.Now you have the tools to determine collection counts of the various schools and a control count of entire holdings. Thidetermine percentages when compared to the control group.Steps to set up for analyzing collections: 1. http://ezproxy.vccs.edu:2048/login?url=http://search.ebscohost.com/login.aspx?direct=true&db=hlh&AN=4911 liveLog into First Search. The Collection Analysis tab should be available. 2. The first place to start is the “Data to Analyze” tab. 3. Select the first school in your list. 4. The collection count of the two schools will appear. 5. Select “Limit Analysis.” 6. Create a subject profile. Once on the profile, clear it and then select subject areas. (Sometimes certain subject profile. That is why it is necessary to clear it first.) You may also enter specific Call numbers, which you have det for a complete analysis. Save. 7. Create as many subject filters as you wish and you are ready for the next stage in analysis.Comparing collections by subject with WCAS: 1. Select “Data to analyze.” (Many times you may need to return here for new search) 2. Choose school. 3. Limit Analysis. 4. Select subject profile filter. 5. Run Search.Data can be entered into an excel spreadsheet and various charts can be created with the data.
  • 7. Here is an analysis across the board of the subjects we selected to analyze. First by collection count: 5000 Agriculture 4500 4000 Veterinary Medicine 3500 Biological Sciences 3000 Chemistry 2500 2000 Communicable Diseases 1500 Dentistry 1000 Engineering and 500 Technology Geography 0 GCC JSRCC JTCC LFCC PCC TNCCHere is a comparison by collection count by the subjects we selected to filter.
  • 8. Here is another comparison converted into percentage contribution to the Control Group.Using this information, we can determine the strengths of each individual school, by graphing the individual schools by thegrouping.

  • 15. It is possible to look at a summary graph of the subjects. It might give the individual school an idea oftheir strengths and weaknesses in general terms. JSRCC 70 60 50 40 30 20 10 0 JSRCCLooking at Germanna’s again, it might be determined our collection is fairly balanced with a strength inChemistry. J. Sargeant Reynolds has a strength in Dentistry and Agriculture. They are also strong inCommunicable Diseases. Germanna’s strengths seem to be Chemistry and Medicine when comparedwith the peer institutions. GCC 18 16 14 12 10 8 6 4 2 0 GCC
  • 16. This is slightly misleading though, since the numbers are the percentages and the subjects do notinclude every subject in the Library of Congress classification system, but rather focused on STEM andvocational subjects of the control group. For a truer perspective of the balance ofGermanna’swholecollection see WorldCat’s“My Library” graphs for individual subjects. It is best to compareGermanna with Germanna, when looking at the distribution of the subject collections.Note our collection is far stronger in the humanities, than in Chemistry. That is why it is best to look atthe individual subjects when comparing collections with other libraries. Then you may see how yoursubject collection compares with that of other peer colleges.There is a way to compare Libraries by Collection Count. And that is meaningful. It answers thequestion, “How does our collection count compare with our select peer college’s?"
  • 17. This shows the actual count size of the collection. When compared with the other schools, Germannawas the smallest in size with all the comparison schools.This is the source of the data from which charts and comparisons can be made. Attached are excelspreadsheets comparing the schools by collection count and by percentage of the comparison group.In addition, Interlibrary Loans may be tracked. Often the results of the highest usage are journal titles,so this is an area that we may want to watch to see if it is appropriate to add a journal title to ourperiodical collection.Comparison can also be made to the Library Journal or College Libraries bibliographies. Unfortunately,this is not a good source for current titles in Scientific Fields. Most titles are at least five years old.Therefore, if currency is important to the subject, it is best to search WorldCat or the VCCSlinc.Appendix.Collection STEM & Other Analyzed by count and percentage of the VCCS group.
