Since libraries are determined to help you maintain privacy, it is our policy to allow records to disappear once items are returned with no fines/fees attached.
However, you can opt to keep your own list. We know this is helpful for many regular library patrons. There are a few options to fit your style.
One way is to use the "My List" feature through your account on the newer catalog. Here is a link to a document that walks you through how to set this up: http://lib.de.us/files/2013/04/Enterprise_My_Lists1.pdf
Another way is through a free, third party resource like Goodreads. This site is very popular for tracking what would have read, are reading, and would like to read. It also gives recommendations based on other Goodreads users.
We know some patrons keep a spreadsheet, such as using Google documents online or simply on paper. Others have a running journal they carry with them so that when they are at the library they can review items they've already read and also have on hand 'wish list' items.
I hope you find these ideas helpful. Let us know what works for you, and if you have any questions about any of these processes, please do not hesitate to ask us.
