This MMP is a partner with the Mountain West Digital Library. This portal displays content from several partners including Montana and it gives our content a wider audience. The MWDL is a content service hub for the DPLA. Our membership in MWDL means our content is also harvested by the DPLA.
Goal: to act as a national digital library that contains the “full range of human expression” from U.S. libraries, archives, and museums and makes it free and openly available to all. The “full range of human expression” in the future might mean more than cultural heritage material—ebooks, data sets, and other kinds of materials.
DPLA is free, meaning there is no registration or subscription required to use it.
By access we mean that DPLA is a portal that offers users metadata (or records) and content previews (like thumbnails). If a user wants to see a full digital object, they are referred back to a hosting institution’s website. DPLA does not have full digital objects. I’ll show you how this works later on in the presentation.
So what type of stuff can I find in dp.la?
Images
Images of objects.
Posters and other print media.
Maps.
Moving images and sounds recordings
Text, including books, periodicals, newspapers, correspondence, various governmental records, obituaries, and more.
We describe DPLA’s mission in three ways (or in terms of 3 Ps):
First, DPLA is a portal that delivers resources through different searching and browsing possibilities. Far more than a search engine, the portal provides innovative ways to search and scan through the united collection of millions of items, including by timeline, map, virtual bookshelf, format, subject, and partner.
Secondly, DPLA is a platform that enables new and transformative uses of our digitized cultural heritage. With a set of development tools and maximally open data, DPLA can be used by software developers, researchers, and others to create novel environments for learning, tools for discovery, and engaging apps.
Thirdly, DPLA is an advocate for a strong public option in the twenty-first century. For most of American history, the ability to access materials for free through public libraries has been a central part of our culture, producing generations of avid readers and a knowledgeable, engaged citizenry. DPLA works, along with like-minded organizations and individuals, to ensure that this critical, open intellectual landscape remains vibrant and broad in the face of increasingly restrictive digital options. DPLA seeks to multiply openly accessible materials to strengthen the public option that libraries represent in their communities.
This presentation is about how to use the portal, or the website itself, but you can find more information about the other two Ps at dp.la/info.
The DPLA homepage. From here you can search the library via a standard search box, search the map or timeline, view books on the bookshelf, dive into curated exhibitions on topics of national interest, and browse through a range of apps built on top of DPLA.
Let’s start first by getting a feel for how to search…
To begin your search, simply type in a keyword or keywords. By way of example, I did a search on “baseball”…
This is the search results page. You’ll see that we got over 12,000 results from dozens of different organizations! Yowza. Before we refine our search, let’s unpack this screen a bit.
Record snippets are on the right hand side. This contains a thumbnail of the resource, title, creator, date, and a description where available. Clicking on the title or thumbnail will bring you to the record for that resource, but if you want to go directly to the object itself, click “view object”. It’s important to remember that this will bring you to another website, the hosting institution for the resource.
You can sort by relevance, A-Z/Z-A, or newest-oldest/oldest-newest.
Refinements are on the left-hand side. This allows you to pull out items that are of particular interest to you, based on which refinements you choose. We’ll dig into this next.
Pleased with this particular search? Save it! More on this later.
Now, let’s narrow down our search a bit. Using the facets in the left hand menus, you can narrow down the results list by:
Format
Contributing Institution
Partner
Date range
Language
Location
Subject (as in assigned subject headings)
Let’s say we wanted just images about the Brooklyn Dodgers. To do that, we can click “image” in the format pane and then “Brooklyn Dodgers (Baseball team)” in the subject pane. If you wanted items from a particular date or place, you could do that as well under their respective refinement panes.
And so, with those refinements in place, we’ve narrowed our search down to 87 images about the Brooklyn Dodgers.
Now that we’ve brought up a manageable set of results, let’s go ahead and check out an item. This is the item detail page. It contains the DPLA record and a thumbnail for the item. The record includes all the information the partner has given us as well as some added information, often time and location information.
When you’re ready to see the full digital item – remember, DPLA contains just the records, not the full digital items –click on “View Object” or the URL in the record. This will bring you to the partner site that hosts the item. In this way, DPLA increases traffic for partners by providing another point of access to their content instead of taking from that traffic. Let’s click “view object” now…
Since this object is stored at Digital Commonwealth, a DPLA partner, we’ve been brought to the object on their site. This is representative of how you will interact with items in the entire DPLA.
Through the DPLA portal, users can save and share lists of records that they have discovered or specific searches they have performed.
Although there is no account required to use DPLA, users might want to create an account for the purpose of selecting and organizing their findings. Users can create multiple lists and keep them private, or share them publicly via URLs.
Once you’ve created a DPLA account or logged in, you can access the list interface by clicking on your profile/account. Creating a new account is as simple as clicking “Add New” under the “Save Items & Lists” tab to the right of “Your Account”.

DPLA also offers a map interface that allows users to see records organized by location. One very common misconception about the DPLA map is that it organizes records geographically by the institutions they come from; rather, the item’s location represents the place where it comes from or was created. For example, a photograph taken of a place in Phoenix Arizona but digitized and hosted by the Digital Library of Georgia would appear on this map in Phoenix. Again, not all records in DPLA have location information.
The dots represent items. You can refine what appears on the map by using the refine pane on the left-hand side.
Zooming into any point on the map produces a refined set of items. Here’s an example of how the map responds to us zooming into the area around Denver, Colorado. Clicking on an orange dot brings up an item or a scrollable list of items.
The DPLA Timeline similarly uses available time information—year, month, day—to chart over time. Using the red slider, a user can capture a particular period of time that will display in the blue section at the bottom. Within this section, they can click on search results for a particular decade or a particular year (indicated by the vertical bars—longer bars have more results). Only records with time data are shown through the timeline interface. This is a large portion but not all the relevant records in DPLA. DPLA works hard to enhance DPLA records with time and location information when possible, but for some we will never know.
Like with the map, you can refine the timeline’s offerings by using the refine pane on the left-hand side. Here’s what the Timeline looks like after a bit of winnowing down.
Some item detail pages offer the option of viewing the item on the timeline, like this record, allowing you to see the item in a broader context.
Note that not all records have this option; only those items with time information can appear on the timeline.
Said record on the timeline appears next to other items from that year.
DPLA Bookshelf is designed to look like a book stack that visitors can browse using the red arrows. Through Bookshelf, users can see book and periodical results relevant to a search. Like the map and the timeline, Bookshelf shows only a portion of the content related to the search—in this case refined by type.
This is a typical record using the Bookshelf. On the right you see that Bookshelf will also return results for “related image” which allow the user to see image content alongside books and periodicals.
Finally, we have DPLA “exhibitions.” They work with DPLA content from multiple institutions around a topic of national significance. Exhibitions offer an opportunity to create juxtapositions between items, use them in narratives, and give them useful context. Exhibitions thus far come from our partners, the digital curation pilot project with MLIS students, and in the future will come from our Gates-funded Public Library Partnerships Project which offers digital skills training and content aggregation avenues to public libraries.
Here’s a screenshot of our most recent exhibition about the Golden Age of Radio, for one example. You can see that the exhibitions are arranged by theme, which each theme containing a number of sub-themes.
This is an example of a typical exhibition sub-theme. Notice the items on the right-hand side, with the contextual narrative on the left. Other exhibition topics include:
European immigration to the US
Prohibition
Activism in the US
Native American history in the Minnesota area
The New Deal
US National Parks
And more!
Technically inclined folks use our open API and open data (or records and thumbnails) to build new apps—for visual discovery, to play well with existing library discovery services like EBSCO, for mobile use. We encourage them to use DPLA data and tools to make something new. For example, the DPLA Search Widget is a simple piece of code that can be added to any website to create a DPLA search box.
These apps are:
(L) Open Pics - a mobile app that allows you to find DPLA images related to your own location.
(R) Serendipomatic - allows you to paste in text to discover related results from DPLA, but also Europeana, Trove, and Digital NZ.
