However, this is complicated by variations in the way page numbers are stored. An alternative involves using pagination, because the often large page numbers in scientific journals, in combination with other fields, can serve as a type of unique identifier. Thus, they cannot be relied upon to identify duplicates. When they are present, they often cannot be exported easily. However, these identifiers are not present in every database.
Unique identifiers for journal articles are digital object identifiers (DOIs) and PubMed IDs (PMIDs). A recent overview article compared existing software programs but found that none was truly satisfactory. In the authors' opinion, these methods are either very time consuming or impractical, as they require uploading large files to an online platform. Several articles have been published recently on de-duplication methods. They typically remove duplicate records to reduce the reviewers' workload associated with screening titles and abstracts sometimes the reviewers remove the duplicates.
When conducting exhaustive searches for systematic reviews, information professionals search multiple databases with overlapping content.
