16 Directions, instructions, memos, letters, e-mails, articles (in newspapers, magazines, newsletters, professional and scholarly journals), books, manuals and reference materials, bills, invoices, financial statements, diagrams, maps and schematics.
2. Journal manual search and reference lists: The computer search was supplemented with manual search of reference lists of all available review articles, primary studies, abstracts from meetings, and bibliographies of books.
It is likely that the manual annotation and reference measurements contain some errors that affect the reported performance.
We supplemented this work with manual searches and reference backtracking.
Electronic searches were supplemented by manual searches and reference linkages.
Relevant literature will be identified from systematic searches of electronic databases, manual searching and reference checking.
Manual searching and reference checking resulted in the identification of 3 additional studies that were reviewed as well.
This was regularly used during training (where each individual team member was required to read the manual) and for reference during field work.
Manual curation and referencing against the recently released genome v2.0 were conducted to exclude loci lacking a conserved motif (HXXXD or DFGWG), loci that represented redundant, possibly allelic copies, and loci resembling spurious gene models (see Methods).
