The library catalog contains books, e-books, journals, newspapers, magazines, manuscripts, audio-visual material, scores, maps, government documents, databases, and more!

Linked subjects in the catalog are like #hashtags

Records for books include linked subjects, which work similar to #hashtags. If you click on a linked subject, you will return results from the catalog of more books on that same subject.

• Pro-tip: If you have found only ONE book, or if you have a book from your syllabus, look for a linked subject to identify other books from Yale Library on that same topic. You might find something better!

A book's call number tells you where a book is located in the library.

1. Read the 1st row of a call number alphabetically (A, AB, C) and then as a whole number (1, 2, 34).

• Use the stacks directory (usually located at the entrance to a library or the book stacks) to navigate to the correct floor based on the 1st row letters then navigate to the correct aisle based on the letter and number.

2. When you are at the correct bookshelf, read the 2nd row letters alphabetically (A, AB, C) and read the numbers as a decimal (.01, .11, .9).

3. The third row can be the year of publication (1947, 2012) or an edition (v1, v2) and will be arranged chronologically.

If you need help or can't find your book, try the "Request recall or delivery" option in Orbis and Quicksearch -- we'll get the book for you!
