What's in your collection?

Are you familiar with the Collections area of HathiTrust?

http://babel.hathitrust.org/cgi/mb

There are currently 940 public collections created by users and library staff members at partner institutions, including several we have featured. HathiTrust collections provide a way to aggregate digital items related to a common theme, or associated with a given physical collection or location (for instance, the University of Michigan has created a collection of its Hatcher Graduate Reference reading room). Items can be added to a collection from HathiTrust full-text search results pages. Once they have been added to a collection, the full-text and bibliographic metadata of items can be searched independently of the larger repository. Items in collections can also be quickly copied to new or existing collections. These features make collections an easy way to refine a set of search results, share batches of items with others, or (in the case of the Michigan Graduate Reference collection), allow staff and users to search within specific collections to find the book with that one particular index or obscure term that they can pull from the shelf for more information.

Staff at some of our partner institutions have been talking about how great it would be to have even more high-quality collections to help demonstrate the usefulness of this feature (and be used!). We'd also like to explore how this kind of feature could better support library needs.

It’s easy to create a collection

Once you are logged into HathiTrust (either as a member of a partner institution or using a University of Michigan Friend Account), you can easily create collections when viewing a volume or from full-text search results as shown below:

 

 

We can help

Because large collections can be somewhat cumbersome to create manually, we can work with you to help build them! To create a custom collection, we need to know the specific the items that are desired to be included. We can work from a list of item identifiers, or from one or more search queries. Item identifiers for large collections, or collections made from criteria that are not easy to search for can be obtained using one of the methods below:

  1. HathiTrust's tab-delimited metadata files. These files are an inventory of repository holdings, containing a variety of identifiers for volumes (ISBN, LCCN, OCLC, etc.), copyright information, and limited bibliographic metadata for each volume in HathiTrust. A description of the files is available at http://hathitrust.org/hathifiles_description.
  2. HathiTrust Data API. In addition to retrieving entire volume packages from HathiTrust (including images and OCR), the Data API can be used to find ids for volumes digitized from a particular source. The University of Michigan has built a demonstration application using the Data API that illustrates how this can be done. Please see http://www.lib.umich.edu/two-over-threehundred.

Custom collections

Here are some examples of collections that have been custom-built. If you haven’t yet become familiar with our Collections feature, give it a try. If you are, and have some great ideas for collections but have had trouble making them, give us a holler and we can point you in the right direction or help you create it.

  • Collections built from one publication -- United States Congressional Serials Set: http://babel.hathitrust.org/cgi/mb?a=listis;c=1597493732
    • Given the title, we were able to locate all items associated with that title in HathiTrust and build a collection.
  • Collections built from a search term in the HathiTrust catalog -- Ancestry and Genealogy: http://babel.hathitrust.org/cgi/mb?a=listis;c=332123463
    • This collection was based on a catalog search for full view items where "genealogy" occurred anywhere in the bibliographic record. The owner has added items individually since the collection was created.
  • Collections built on holdings information in a partner catalog -- UM Hatcher Graduate Reference: http://babel.hathitrust.org/cgi/mb?a=listis;c=30688098
    • The list of ids for this collection was assembled using location data from the University of Michigan Library.
  • Collections built from analysis -- English Short Title Catalog: http://babel.hathitrust.org/cgi/mb?a=listis;c=247770968
    • HathiTrust is collaborating with the ESTC to determine volumes in a candidate set (English language volumes published before 1800), are both in the ESTC catalog and in HathiTrust. The matching volumes are included in the ESTC collection.

Note that once collection(s) are built, we will transfer ownership to the requester so the collection(s) can be updated and maintained.
