A:
Your LSC User Account will allow you to submit 25 active requests at one time. HOWEVER, paging for off-site materials (materials housed at SRLF or at the Biomedical Library) is limited to 5 boxes/items per day.
Most archival materials are held off-site.
Materials housed on-site can usually be paged same-day and are limited to an additional five boxes/items per hour.
Please see: How can I tell whether LSC materials are located off-site or on-site?
