We've upgraded the functionality for importing bibliographic files on Grafiati and now offer support for uploading multiple files simultaneously. References from all the uploaded files will be automatically added to your current bibliography.
Furthermore, we've made significant improvements to the algorithms for extracting information. Even if a file is damaged or contains errors, we'll make an effort to recognize and process the existing data.
Please be aware that the import feature is accessible for files in either .bib or .ris format.
