-
Conduct a privacy/confidentiality audit.
-
Gather the minimum amount of patron information needed for library operations.
-
Retain information connecting a user to a particular transaction only as long as needed for normal operations.
-
Restrict access to patron information to a limited number of appropriate library personnel.
-
Write use and privacy policies that tell patrons what they can do to protect their privacy.
-
Educate staff on confidentiality policies.
-
Rather than using sign-up sheets for people using library computers, use a "pass system" in which the patron shows an ID, but the ID is not recorded.
-
Avoid practices and procedures that place patron information on public view.
-
If the library uses an outside Internet Service Provider, choose one whose practices best match the library's privacy policy.
-
When using commercial document suppliers, make sure the library is not required to identify patrons requesting information.
-
If the library buys an Internet filtering product, be sure the company will not sell its database of Web sites visted by patrons in the library.
-
Don't include patron names on interlibrary loan requests sent to other libraries.
-
Find ways to separate patrons' names from interlibrary loan records.
-
Set automated circulation systems to purge borrower information when items are returned.
-
Delete old Web server logs.
-
Check with software vendors to see if they have tools for making the library system logs anonymous.
-
On public workstations, use boot routines to clear caches, temp directories, and recent history browsing files.
-
Use image programs to wipe out and recreate hard drives of public terminals each night. This will get rid of installed programs, cookies, and other identifiers.
-
Delete cookie files or set browsers to reject cookies.
