Walt Nickerson has recently published updated versions of his four macro books:

Walt’s Macros

The long list is in alphabetical order, so look in the middle for M: Macro book: Essentials; Macro Book: Extras1; Macro Book: Extras2; and Macro Book: MacroTools.  There is also, right above these, a handy list of all the macros in the four books, “Macro book listing.”

Terry Reese announced new additions to MarcEdit on April 30. He has added a new tool, UNIMARC Tools, for moving data between MARC21 and UNIMARC, and a new option has been added to the Replace function.

Update on MarcEdit:  Terry has just (as of today, May 13) announced that he plans a few more updates for the weekend.  If you use MarcEdit and want to be up to date, it would be a good idea to subscribe to his list, MARCEDIT-L (MARCEDIT-L-request@listserv.gmu.edu).
