我的两篇都是先online，也没有页码。过几个月才有

现在爱斯维尔的文章开始采用文章编号了，不再统一分配页码了。

已经改革了，用文章号就可以了，1-8这个不用，这个是你文章的页数

看一下文章状态是不是处于 in press.

文章编号是大势所趋，例如BT在3月份开始采用。

publisher’s note
introducing article numbering to bioresource technology
within the publishing industry, article numbering has emerged as an easy and efficient way to cite journal
articles. article numbering has already been successfully rolled out to elsevier’s multidisciplinary open
access journal heliyon, as well as more than 200 other journals, and has been well received by the academic
community. based on that positive feedback, we are now pleased to introduce article numbering to bioresource
technology from may 03, 2019.
what is article numbering?
a unique article number is an abbreviated form of an article’s doi - digital object identifier. citing an article
with an article number is very simple: the article number is used instead of the page range in the citation.

while journal volumes and issue numbers will remain in place, article numbering will now play the key role
in identifying specific articles. the introduction of article numbers brings several benefits for the journal and
its readers and authors.
benefits of article numbering
• more flexible reading: article content can be optimized based on the device used to access it,
supporting reading on-the-move, without needing to know how many traditional print pages the
article takes up.
• improved accessibility: articles will be available in a variety of download options. for example,
pdfs in the future can be generated in large font, or a dyslexia-friendly font, to suit individual user
needs.
• increased options for grouping related content: in online collections and special issues, articles
can now be placed in any order, helping readers to identify papers relevant to their research
interests faster.
• faster publication: with article numbers, the version of record of the article is online and citable
as soon as the proof corrections have been incorporated, ensuring readers have access to the latest
research faster.
we are delighted that bioresource technology ‘s readers and authors will now enjoy these benefits.
