Preparing Additional Files
Although Cardiovascular System does not imply any restrictions on the length of data in a paper, but still authors may wishes to provide data sets, tables, movie files, or other information as additional information. These files can be uploaded using the 'Additional Material files' button in the manuscript submission process.
The maximum file size for additional files is 20 MB each, and files will be virus-scanned on submission.
Any additional files will be linked into the final published article in the form supplied by the author, but will not be displayed within the paper. They will be made available in exactly the same form as originally provided.
Authors should mention the following information for all additional material at the end of the document in a separate section:
- File name
- File format (include correct file extension and a URL of an appropriate viewer if format is unusual)
- Title of data
- Description of data
Additional data files should be referenced clearly by file name within the text of the article, e.g. 'See additional file 1: Movie1 for the original data used to perform this analysis'.
Additional file formats
Preferably, additional files should be in usual file formats performing on widely usable and available tools and platforms. Avoid platform-specific file formats. The following are examples of suitable formats.
PDF (Adobe Acrobat)
SWF (Shockwave Flash)
XLS (Excel spreadsheet)
CSV (Comma separated values)
All references must be numbered consecutively, in square brackets, in the order in which they are cited in the text. Reference citations should not appear in titles or headings. Each reference must have an individual reference number. Please avoid excessive referencing. If automatic numbering systems are used, the reference numbers must be finalized and the bibliography must be fully formatted before submission. Irrespective to the number of authors in the citation, the reference list should contain all named authors. Journal abbreviations should be made in accordance to Index Medicus/MEDLINE.
Citations must refer only articles or abstracts that have been published and available through public servers. Any unpublished abstracts or data and personal communications should not be included in the reference list, but may be included in the text and referred appropriately indicating the researchers involved. Obtaining permission by a letter from the relevant authors to quote personal communications and unpublished data from the cited author(s) and it is the responsibility of the author to acquire them.
Herbert Open Access Journals uses the numbered citation (citation-sequence) method. References are listed and numbered in the order that they appear in the text. In the text, citations should be indicated by the reference number in brackets. Multiple citations within a single set of brackets should be separated by commas. Where there are three or more sequential citations, they should be given as a range. Example: "... now enable biologists to simultaneously monitor the expression of thousands of genes in a single experiment [1,5-7,28]." Make sure the parts of the manuscript are in the correct order for the relevant journal before ordering the citations.
Authors are requested to provide at least one online link for each reference (preferably PubMed).
Because all references will be linked electronically as much as possible to the papers they cite, proper formatting of the references is mandatory.
