Building a technical library

Wed Jun 1 03:46:26 UTC 2016

Looking to develop a technical library for about 15 staff members all under
the same roof.  Subject matter would focus around Juniper/Junos, TCP/IP,
dwdm, python, java, and expand from there.  The O'reilly Safari service
looks rather comprehensive, although at $400/user there may be more value
buying hard copies and own them outright (or at least until they walk
away).  Are there other online resources that offer a good value?  Other
experiences weighing the pros and cons?

Thanks,
Chris
