Preservation guidance, conservation referrals, and practical advice for maintaining the condition and integrity of rare books, manuscripts, and private library holdings.
Whether you are verifying a recent acquisition, planning a deaccession, or beginning a new bibliographic project, the care desk at Tetra Biblios can point you toward the right service and the right sequence of work.
For condition queries, provenance questions, or to arrange a conservation referral, reach the practice directly. The desk is staffed during archive hours, and messages left outside those times are answered on the next working day.
For provenance questions, condition assessments, or cataloguing inquiries, write to info@tetrabiblios.com or call +60 16 300 2417. The practice is based at Hala Lapangan Perdana 16, Ipoh, Perak, 31650, Malaysia, and welcomes scheduled visits for estate libraries and private collections. Dealers and auction-house partners typically receive a reply within two working days.
General bibliographic enquiries are answered within three working days. Provenance verification and condition reports require a preliminary review of photographs or catalogue records, so allow up to five working days for an initial assessment. For urgent deaccessioning decisions or auction deadlines, mention the timeline in your first message and we will prioritise accordingly. See the contact page for the full consultation schedule.
