Searching for transcriptions

In the collections dropdown next to the search box, narrow your search to Manuscripts--or narrow it even further by selecting a sub-collection, like Pre-1701 manuscripts or Newdigate family collection of newsletters. From the object type dropdown right below the search box, select Search for pages. This means your results will be individual image records, which are the record types that will have transcriptions when available. Removing object records from the results clears out some noise from the results list. In the search box itself, remember that spellings vary, and make liberal use of OR searching to search on multiple spellings. When looking for recipes with garlic, for instance, you may want to search for garlic OR garlick, as below:

Working with media groups

For instructions on exporting media groups from Luna, see https://folgerpedia.folger.edu/Migrating_media_groups_from_Luna

Before beginning your work, make sure you're signed in.

Select Add a new media group from the Create drop-down in the menu. This will open a form. You must give your new media group a title, and you can choose to add a description. You can begin to add items using the box below the description field, but we're not recommending that you use it right now. At the very bottom of the form, there's a check box. Check to make your media group public, or leave it unchecked to keep it private. Media groups are still under development. It's safe to make and use them, but we are recommending that all media groups are left private for now: in their current state, any user is able to edit public media groups. We will let you know when it's safe to begin using public media groups! Click the save button to finish creating your group.

URL structure

Image records

URLs for individual images are formed by appending the digital image file name (removing any leading zeroes) to the end of the base URL digitalcollections.folger.edu/img

The digital image file name is number of up to six digits, and is the very first field in the image record on both the new digital collections site and on Luna:

By appending digital image file name 72418 to the base URL above, we get the link digitalcollections.folger.edu/img72418

Microfilm image records use the same style of file name, and their URLs are constructed in the same way. Bindings images records use a different and more complicated style of file names, so they instead use a default URL structure that is not predictable based on external IDs.

Standard object records

Whenever we have more than one image for an item--multiple pages in a book, for instance--we will also have a parent record linking all of the individual images together. The URL for these object records is formed by appending the bibliographic ID, a hyphen, and the holdings ID to the end of the base URL digitalcollections.folger.edu/bib

The bib and holdings IDs can be found in the catalog. The catalog URL for STC 6857, Tectonicon, is catalog.folger.edu/record/163490 The number at the end of the catalog URL--163490 in this example--is the bib ID. If we look at that same record in the MARC view (by appending /export/tm to the end of the catalog URL), we see that bib ID again at the top of the record, in the 001 field. Towards the bottom of the record, in field 852 subfield 7 ($$7), we can find the holdings ID--156904 for this example.

By appending these IDs, separated with a hyphen, to the base URL above, we get the link digitalcollections.folger.edu/bib163490-156904

Microfilm object records

Microfilm object record URLs are formed in nearly the same way as standard object URLs. Because we may sometimes have both standard and microfilm images of the same item, we need to differentiate between the two. We do that for microfilm object records for including mf in the base URL: digitalcollections.folger.edu/mf_bib

The URL for the standard object record for V.a.269, which has bib ID 231225 and holdings ID 280167, is digitalcollections.folger.edu/bib231225-280167, and the URL for the microfilm object record for the same item is digitalcollections.folger.edu/mf_bib231225-280167

Bindings object records

Bindings object records are formed just like microfilm object records, replacing the mf prefix with bindings, making the base URL for these items digitalcollections.folger.edu/bindings_bib

An example will be added shortly.
